This Sunday, March 26, Fox will air an episode of The Simpsons written by and guest starring Ricky Gervais (BBC's The Office and HBO's Extras.) He'll be playing a David Brent-like character who seduces Marge when the two of them are paired up on a Trading Spouses-type show. It's a bit of an experiment for the show (it was creator Matt Groening's idea) and Gervais told the press he's prouder of this episode than anything else he's done. It's hard to imagine it won't work, but if it is as funny as it sounds, it could shoot up to the top of our list of the greatest Simpsons guest stars of all-time (recurring characters, like Kelsey Grammer as Sideshow Bob, or Joe Mantegna as Fat Tony don’t count.)

20. U2 – "Trash of the Titans" – Homer tries to boost his campaign for sanitation commissioner by crashing a U2 concert (back in the PopMart days.) But he finds the band is an unwilling audience.

Memorable Exchange:Bono (To Homer): "Ray Patterson is a fine civil servant. Why should the people vote for you?"The Edge (aside, to Larry Mullen): "Here we go. What do you say we slip out to Moe's for a little bit?"Adam Clayton: "Can I come too?"The Edge: "No."

19. Spinal Tap – "The Otto Show" – Spinal Tap play a gig in Springfield that ends in chaos, inspiring Bart to dream of one day becoming a guitar hero himself. Of course, one of the members of Spinal Tap (Derek Smalls) is played by utility cast member Harry Shearer (voice of Mr. Burns, Principal Skinner, and Ned Flanders,) so it's not like they were tough to get.

Memorable Quote:David St. Hubbins: "Good night Springton. There will be no encore."

18. James Taylor - "Deep Space Homer" - While "average-naut" Homer Simpson is floating in space, NASA brings in folk-pop-rocker James Taylor to sing to the crew (which includes Buzz Aldrin.) Homer reacts accordingly by expressing his awe of "former President James Taylor."

Memorable Quote:Taylor: "Listen, Aldrin, I'm not as laid-back as people think. Now here's the deal: I'm going to play, and you're going to float there and like it."

Memorable Exchange:Homer: "Well, what should I do? Should I meditate? Should I get rid of all my possessions?"Coyote: "Are you kidding? If anything, you should get more possessions. You don't even have a computer!"

16. Ann Bancroft - "Fear of Flying" - Bancroft plays Dr. Zweig, the therapist Marge consults to help her get over her fear of flying.

Memorable Quote:Dr. Zweig: "The Monkees weren't about music, Marge. They were about rebellion and political and social upheaval!"

15. Jackie Mason - "Like Father, Like Clown" - Mason plays - what else? - a rabbi. He's Rabbi Hyman Krustofsky, the estranged father of Herschel Krustofsky, a/k/a Krusty the Klown. Rabbi Krustofsky disowned his son after he discovered his ambition to become an entertainer, and Bart and Lisa take it upon themselves to reunite the two.

The Lost City In 1990, Sydney Pollack refashioned Michael Curtiz’s Casablanca , setting the action during a period of political upheaval in Havana , with Robert Redford doing little to erase memories of Humphrey Bogart.

Review: Last Chance Harvey Between them, Dustin Hoffman and Emma Thompson have four Oscars, so it's hardly surprising to see them paired up in director Joel Hopkins's attempt at Oscar bait.

Review: Batman: Arkham Asylum Although Heath Ledger fully deserved the Oscar he won (posthumously) for his portrayal of the Joker in The Dark Knight , a less heralded actor had staked a claim to the character years before. On Batman: The Animated Series , Mark Hamill brought a fearsome edge to the role that outstripped any previous dramatic effort.

Cinema paradisos Here's the dilemma: you love movies, but you also love the idea of taking a vacation to one of the many inviting resorts that New England has to offer — the beaches of Cape Cod or the Islands, picturesque towns in Maine or Rhode Island, or even the cultural and historical enclaves of Boston itself.

Cursed films At some point while watching the features in the Harvard Film Archive's "Le Film Maudit" ("cursed films") series — perhaps during the "Circle of Shit" chapter in Pier Paolo Pasolini's SALÒ, OR THE 120 DAYS OF SODOM — you might ask yourself, which is more cursed, the movies or anyone unfortunate enough to be watching them?

Politics as usual? Conspiracy, corruption, catastrophe — politics and world events sure can be exciting. Even the mainstream news is taking an interest.

The girls of summer It’s summer, so no one’s surprised at the onslaught of sequels, adaptations, or even movies based on toys. But films with Oscar-caliber women’s roles?

Cowboy down After the heights of Brokeback Mountain , will the course of gay cinema be all downhill?

REVIEW: THE NEWSROOM | June 20, 2012 The Newsroom is a dose of concentrated Sorkin, by turns maddening and exhilarating.

HBO'S VEEP NEEDS MORE MEAN | April 23, 2012 Reality, right now, is so absurd that almost everyone has already adopted a "laugh-to-keep-from-crying" approach to the news. We don't need someone to tell us how truly horrifying our political landscape is. So what's a satirist to do?
